6 Claims. (cl. 72-101) This is a division of my application Serial No. 543,356 filed July 3, 1944, which is a continuation-in-part of my two co-pending applications Serial Number 389,553, filed April 21, 1941 and Serial Number 412,350, filed September 26, 1941, now abandoned, the latter being a division of my application Serial Number 271,901, filed May 5, 1939 and issued as Paten 2,270,297 on January 20, 1942.

Each of the aforementioned parent applications discloses an improved and relatively inexpensive type of wall construction for furnaces, heaters and the like involving the use of prefabricated slabs or sections which form the walls of the heater and comprise a relatively thick layer of heat insulating material covered on one side by a relatively thin layer of denser refractory material.

The present application is more particularly directed to means for suspending the slabs, such as in the walls and/or roof of a heater, and their attachment to a supporting structural framework of metal members or the like. This is accomplished by socket members embedded in and anchored to the insulating material of the slab and detachable clips which secure these anchored socket members to members of the structural framework. The specific means provided for suspending the slabs and securing them to the framework obviates punching or drilling of the latter as would be necessary bolts Or the like embedded in the slabs. They are also constructed and arranged to accommodate minor variations or inaccuracies in spacing, size and contour of the framing members to which the slabs are attached, as well as in the spacing or location of the socket members embedded in the slabs.

The unique and advantageous method and means herein provided of supporting the slabs may be employed to advantage with preformed slabs or panels other than those shown. For example, the attaching clips may be employed to support refractory shapes, insulating slabs or panels not provided with a refractory surface, or slabs or panels comprising a mixture of insulating and refractory materials. The invention with the use of tie assembly of refractory faced insulating slabs or panels such as provided by the invention.

Figure 2 of the drawing is an elevational view, shownprincipally in cross-section, of a portion of the roof and wall of a heater or the like emplaying the features of construction provided by the invention.

Figures 3 and 3A, respectively, are enlarged perspective views of one of the attaching clips I9 and one of the wedges 20 shown in Figures 1 and 2. I

Figure 4 is an enlarged perspective of one of the attaching clips 2i shown in Figures 1 and 2.

Figure 5 is an enlarged perspective view of a socket member such as the members I3 of Figures 1 and 2.

Referring now particularly to Figures 1 and 21, the slabs or panels which are designated by the reference numerals I0 each comprise a substantial thickness of suitable heat insulating material indicated at II and a lesser thickness I2 of suittherefore embraces and specifically contemplates such other uses of the supporting or suspending means which it provides.

The features and advantages of the invention will be more fully explained with reference to the accompanyin diagrammatic drawing. In the drawing Figure 1 is an isometric of an able refractory material the entire surface of the one side of the slab and is to, preferably without any intermediate adhesive layer, mechanical keys, metal ties or the like. Preferably, the slabs are cast or pressed in a suitable form or mold in which both the insulating and refractory layers are placed and the socket members I3 are embedded in and anchored to the insulating layer as the slab is formed. Thus, the entire preformed slab or panel comprises the insulating layer II, and the refractory which is applied over insulating material on directly bonded there- Members I3, as shown in Figure 2, are sufficiently shallow that they leave a substantial thickness of insulating material between the back side of each of members l3 and the refractory layer I ll of the slab.

As shown in Figures 1 and 2, the slabs are assembled in edge to edge relation to form the walls and/or roof of a furnace structure, heater, oven or the like with the refractory face I2 disposed on the inner or hot side of the wall. At a substantial distance from the hot side of each slab a groove, which is indicated at I4 in Figure 1, is formed or cut within the body of the insulating layer II about the entire periphery of the slab. In assembling the slabs in the wall, a spline I5 is placed within the grooves I4 and the spline along each edge of adjacent slabs is embedded partly in the groove of one slab and partly in the groove of the other so as to break the joint between the slabs and serve as a seal to prevent the escape of combustion gases or the like from the heater and to prevent the infiltration of air through the wall.

In constructing the heater a suitable framing of metal I beams or the other structural shapes, such as indicated at It and I! in Figure 2, is erected. Several of the upright members or columns i6 are provided at spaced points along the side walls and are surmounted by the roof beams W and suitably attached thereto by welding, bolting, riveting or the like in any convenient manner not illustrated. Metal angles or the like It are provided at spaced points along the length of members lfiand ll running transverse to and extending between the adjacent main framing members it and ii. The slabs it are then placed inside the structural framework and are securely anchored to members it by means of the clips 59 and 2!, the wedge-like member and the socket members it, which latter are embedded in the slabs before their erection.

It will be noted with reference to Figure 1 that, in the particular case illustrated, four of the socket members It are provided in each of the slabs it and are disposed adjacent the four corners of the slab. These members it are substantially aligned in vertical and horizontal rows when the slabs are in place in the wall. In the vertical side walls of the structure the member it of each set of clips is secured to one of the members it along the bottom edge of a slab which is disposed immediately above the member it to which this clip is attached, while clip 2E of this same set is secured in one of the socketlike anchoring members it adjacent the top edge of the nearest lower slab.

Clip it (Figure 3) has a T-shaped head at one end thereof, formed by the cross-bar 22, which slips into the enlarged lower portion of a keyholelike opening provided in the outer face of member l3, and the'adjacent neck 23 of clip is is then slipped upwardly into the narrower or slotlike upper portion of said opening in member H3. The opposite end 24 of clip is is substantially hook-shaped and fits over the outer edge of the upper leg of angle it, as used in a vertical wall.

Clip iii (Figure 4) is substantially L-shaped having a T-shaped head 25 at the outer end of its horizontal leg (as used in a vertical wall) which is engaged with its companion member it in the same manner above described as the T-shaped head 22 of clip l9. A substantially hook-shaped portion 26 is provided on the back side of and at the junction of two legs of clip 2! and engages the under edge of the vertical leg of angle IS. The vertical leg of clip 2| (as used in a vertical wall) has an enlarged substantially wedge-shaped outer end 21 adapted to pass through a substantially wedge-shaped opening 28 provided in the leg of member I9 which runs parallel to the upper leg of angle l8. Wedge 20 (Figure 3A) is forced or driven into the opening and i9" are employed adjacent the juncture oi? the side wall and roof. That portion of clip l9 which extends downward from the member I8 is straight instead of being bent at a right angle and is provided with a cross-bar 22' at its lower end which forms a T-shaped section engaging the socket member 93 nearest the juncture of the roof and side wall. A special clip 2| similar to clip 2| is employed in conjunction with the special clip l9 and difiers from the members 2! only in that the leg which carries the T-shaped head is eliminated.

The last set of clips for the side wall slab most adjacent the roof comprise one of the regular clips 2| and the special clip 09''. The latter is constructed as shown in Figure 2 to hold in place a relatively narrow sheet 32 of hard pressed asbestos board, metal or the like which fits along its lower edge into the top groove in the uppermost slabs on the side wall and substantially abuts the edge of the adjacent slabs in-the roof, preferably with a small space therebetween which may be filled with a suitable mastic, refractory material or the like as indicated at 29.

The socket member l3 which is embedded in the insulating layer of the slab may, as indicated in Figure 5, be of a box-like construction with a keyhole-like opening provided in its front face and with suitable ears 3i extending outwardly from its box-like body to serve as anchors to prevent the socket member from pulling from the insulating material.

28 of member l9 substantially parallel to and on that side of the vertical leg of member 2| which is opposite the angle l8. Thus, as shown in Figure 2, the wedge-like head 2'7 of clip 2! is held in place above the upper leg of angle 18 and the hook-like portions 24 and 26 of the respective clips l9 and 2| are keptin engagement with the leg of the angle l8 by the wedge 20.

The roof construction, as illustrated in Figure 2, is similar to the wall construction above described, except that the angles l8 and the clips l9 and 2| are oriented 90.
